* Added cache updating behavior for GetShard
Customer are occasionally seeing messages about being unable to
retrieve shard information, which is logged as a warning. This change
will allow the shard map to be updated even when there is no re-shard
operation.
This now triggers a shard list update if there is 1000 cache misses,
or a cache miss occurs when the cache is more than 30 seconds old.
For Kinesis the updates will use ListShards, and for DynamoDB Streams
it will continue to use DescribeStream.
* Adjust some logging, and the zeroing of cache misses a bit
Only log about cache refresh if it's the thread doing the cache
refresh. If after synchronizing the shard is present, accept that
someone else loaded the shard map, and move on.
If the cache was reloaded, and the shard was found the current thread
will reset the cache misses.
The warnings for the cache miss was using a modulo of 1000 which is
the maximum value for cache misses, so wasn't to useful.

Allow unexpected child shards to be ignored
now instead of always throwing an assertion if a child shard has an
open parent, consider worker configuration before doing so. if
configured to ignore such shards, do not create leases for them during
shard sync. this is intended to mitigate failing worker init when
processing dynamodb streams with many thousands of shards (which can
happen for tables with thousands of partitions).
this new behavior can be enabled by adding the following to a
configuration/properties file:
```
ignoreUnexpectedChildShards = true
```
* Shutdown that throws an exception will be retried.
Without this change a transient error on shutdown with reason terminate prevents
child shards from starting.
* Fixing the tests for the Shutdown fix.
Fixes#262
Changing the signture of SingleRecordsFetcherFactory to no longer take maxRecords as the parameter to the constructor. Changed the createRecordsFetcher signature to take maxRecords as a parameter. (#264)
